Good Germs, Bad Germs: Health and Survival in a Bacterial World

Public sanitation and antibiotic drugs have brought about historic increases in the human life span; they have also unintentionally produced new health crises by disrupting the intimate, age-old balance between humans and the microorganisms that inhabit our bodies and our environment. As a result, antibiotic resistance now ranks among the gravest medical problems of modern times.

Good Germs, Bad Germs addresses not only this issue but also what has become known as the "hygiene hypothesis"-- an argument that links the over-sanitation of modern life to now-epidemic increases in immune and other disorders.

In telling the story of what went terribly wrong in our war on germs, Jessica Snyder Sachs explores our emerging understanding of the symbiotic relationship between the human body and its resident microbes--which outnumber its human cells by a factor of nine to one!

The book also offers a hopeful look into a future in which antibiotics will be designed and used more wisely, and beyond that, to a day when we may replace antibacterial drugs and cleansers with bacterial ones--each custom-designed for maximum health benefits....more

What a fantastic book to read while sick!

When I started Good Germs, Bad Germs, I had just come down with a respiratory tract infection, and by the time I finished it I had succumbed to a feisty gastrointestinal virus, along with the majority of my family. I lay in bed, imagining staphylococcus aureus leaving its "sweet spot" in my nose and dripping down into my lungs, where it could colonize and cause pneumonia. I noted my bad breath and imagined the streptococcus mutans lining up shoulder to shoulder in my dental plaque, and promised myself I would drag myself out of bed to dislodge them, no matter how ill I felt. I pictured whatever microorganism causing my nausea multiplying rapidly and excreting their nasty byproducts until finally, when my stomach lining reached its toxic threshold, I expelled it all (over and over again. For 12 hours.) Now I am imagining how the landscape of my digestive tract is riddled beyond recognition, the virus having expunged all the protective bacterium that normally call it home. I'm eating yogurt, full of probiotics, trying to repopulate my guts with helpful lactobacilli, so that someday I will be able to properly digest food again. I'm hoping and praying that my natural ecosystem will balance itself out in my favor, soon.

The premise of this book is scary stuff. While we are so, SO fortunate to live in this day and age of sanitation, vaccines, and antibiotics -- the American life span has more than doubled since 1776 -- it seems we are starting to pay the proverbial piper. We in the developed world have increasingly high rates of inflammatory and autoimmune diseases (atherosclerosis, arthritis, diabetes, lupus, MS, etc.,) allergies (both disturbing and life-threatening,) and even depression, all of which were almost unheard of before the 1800's and advent of public sanitation (waste collection, sewer systems, refrigeration, etc.) People in undeveloped areas of the world rarely suffer from these maladies. Of course they also may still die from dysentery or cholera, and before the age of 50, but it is what it is -- have we traded quality of life for quantity of life?

Antibiotics -- stop abusing them! Please, please PLEASE do not ask your doctor for antibiotics when you have a cold. Or even the flu, usually. Antibiotics kill BACTERIA, and the majority of every-day illnesses are caused by VIRUSES. If you take antibiotics when you are suffering from a viral infection, a couple things will happen: 1. You might feel a little better, possibly via placebo effect. But! 2. Your antibiotic will kill lots of bacteria that are beneficial to your body, particularly your digestive system. 3. It can cause antibiotic-resistance among any remaining bacteria, which may prove problematic later on, because apparently bacteria can swap genes and practice all kinds of unfair warfare when they want to dominate. And this will not only affect you and your body, but EVERYONE. I have always known somewhat about antibiotic resistance, and tried to do my part by not using them indiscriminately, finishing my course, etc., but I have naively thought that because I wasn't personally abusing them, they will work for me someday when I need them. Not so. Due to widespread human and agricultural use (DON'T GET ME STARTED ON AGRICULTURAL USE!) virtually every antibiotic out there has encountered resistance, and these antibiotic-resistant bacteria show up EVERYWHERE, even in people who haven't taken antibiotics for years.

Oh, the fear! MRSA ("flesh-eating bacteria",) sepsis, pneumococcal pneumonia, massive infections shutting down organs! Fortunately, the last part of this book gives a little hope. While researchers are every trying to develop new antibiotics, the real promise looks to be in the field of PRObiotics. Our bodies are covered in microbes from the second we are born, and our health depends on the good ones that muscle out the bad ones. If we can promote the growth and colonization of beneficial microbes, there will be no room for the diseases-causing ones. I love one of the last chapters in the book that quotes microbiologist David Thaler, who imagines that we will soon stop waging warfare on germs via all our hand-sanitizers and lysol wipes, and instead deliberately seeding our environment with carefully selected strains and species. "We will no longer douse our hands, faces, and bodies with antibacterial soaps; we will wash them with probiotic mixtures shown to enhance health…. Instead of futilely trying to disinfect public bathrooms, cleaning crews will spray toilets and doorknobs with tenaciously territorial "good" bugs. Subway straphangers will grab onto handholds impregnated with bacteria that kill cold and flu viruses on contact." (pg. 215)

Good Germs, Bad Germs: Health and Survival in a Bacterial World was published in 2007. I don't know how far some of this research in probiotics has gone in the past seven years, but I am hopeful. I do know that our FDA causes everything to move at a snail's pace, so in the meantime, I'll be doing my best not to get sick. (Again.) And as a side note -- this book makes no mention of nutrition, but it's been proven since the time of plagues that those with the best nutrition stand the best chance of survival from all kinds of pestilence.

Good Germs, Bad Germs: Health and Survival in a Bacterial World, by Jessica Snyder Sachs, is an exploration of humans' interactions with bacteria throughout time with an emphasis on modern history and developments of the twentieth and twenty-first centuries, such as the widespread use of antibiotics in people and animals for both therapeutic and non-therapeutive, or preventative, measures.

The book's prologue begins with a narrative about Ricky Lannetti and his battle with antibiotic resistant MRSA, a particularly destructive strain of Staph. This narrative begins Sach's exploration of how humans and bacteria coexist and how this once symbiotic relationship of man and bug is transforming with the development of new antibiotics and evolving bacteria.

Sach explores stories of patients infected with bacteria, patients who use bacteria as part of a CAM (Complementary and Alternative Medicine) treatment, doctors who developed and are developing new antibiotics, food companies exploring the use of probiotics in their products, and microbiologists who are discovering how bacteria evolve, share information, and develop antibiotic resistance.

Unlike many non-fiction science books, such as The Brain That Changes Itself, Good Germs, Bad Germs is organized into seven distinct parts plus a very brief coda, rather than the standard chapters that readers have come to expect.

Sachs' book begins with a brief glossary of seven key terms used throughout the book. The glossary explains these sometimes complex parts of scientific jargon in laymen's terms.

Each of the seven parts in the main section of the book are well-organized and each part includes specific and well researched examples with copious supporting endnotes.

The glossary, coupled with Sachs' accessible writing and concise well titled sections within each part, makes her ideas available to readers of all levels and backgrounds. A specialized advanced degree in science isn't necessary to enjoy reading Good Germs, Bad Germs.

This book is recommended for anyone concerned with the proliferation of antibiotics in our bodies and in our food. Hopefully this book will allow patients to make better informed decisions regarding their use of broad spectrum antibiotics for common ailments and maladies.

Good Germs, Bad Germs is also recommended reading for high school and college students considering majors or careers in the biological sciences, specifically microbiology.

We truly live in a bacterial world. They live in the soil on which we walk, they swim in the water we drink, and they even float on particles of dust in the air we breathe. And for every human cell in our own bodies, there are ten bacterial cells, on our skin, in our upper respiratory tract, and all throughout our gastrointestinal tract, making up the human microbiome. Not only are these bacteria harmless to us, they’re actually healthy for us: industrial agrobusiness raises their animals on antWe truly live in a bacterial world. They live in the soil on which we walk, they swim in the water we drink, and they even float on particles of dust in the air we breathe. And for every human cell in our own bodies, there are ten bacterial cells, on our skin, in our upper respiratory tract, and all throughout our gastrointestinal tract, making up the human microbiome. Not only are these bacteria harmless to us, they’re actually healthy for us: industrial agrobusiness raises their animals on antibiotics because it causes them to gain weight, and when Louis Pasteur tried to raise mice under sterile conditions, they all died.

Which is not to say that we should throw out our antibiotics, stop washing our hands, and drink raw milk, because there are a few strains of Staphylococcus aureus, Listeria monocytogenes, Clostridium difficile, Enterococcus faecalis, Salmonella typhimurium, Shigella dysentariae, and Streptococcus pyogenes that can, and do, make us very sick and even kill us. The problem, however, is that when you use an antibiotic to take out a dangerous bug like Strep, you also raze your microbiome and leave yourself at the mercy of whatever bugs happen to be resistant to the drug you chose. As Rockefeller University microbiologist David Thaler says, “Whenever you make a sterile surface, you become a victim of whatever falls on it. It’s like plowing a field and not planting anything but instead trying to live on whatever weeds happen to pop up.”

The HIV field learned hard lessons about the dangers of serial monotherapy and have essentially solved the problem (in rich countries, at least) with HAART (highly active anti-retroviral therapy), but even if antibiotic-prescribing physicians learned the lesson to never give antibiotic monotherapy, additional challenges remain. Horizontal transfer of resistance genes among bacteria is very easy, so bugs in the microbiome naturally resistant to a couple of the drugs in the combination (and there are so many bugs in the microbiome that the probability of such a bug being resident, certainly among a population of humans, is not so remote) develop resistance to the remaining monotherapy in the conventional way, but then can pass all three resistance genes to any other passing bug, benign or pathogenic. Furthermore, although we frequently blame the development on antibiotic resistance on pushy mothers for demanding antibiotics for viral infections or on children for prematurely stopping taking their prescription, the fact remains that 89% of the antibiotics used in this country are consumed by livestock, and the vast majority of those are not given to sick animals, or even to prevent infection, but given at subtherapeutic doses because, for reasons of which we’re not entirely certain, they promote faster growth (possibly because the livestock’s microbiomes are getting trashed). Not only does giving subtherapeutic doses to healthy animals (of, in many cases, the very same drugs also prescribed to human patients facing life-threatening infections) produce an ideal laboratory for the production of antibiotic-resistant microbes, but this problem is exacerbated by the fact that farms do not face the same strict regulations for processing animal waste as municipalities do for processing human waste, so that antibiotic-resistant microbes, unmetabolized antibiotics, and plasmids containing antibiotic-resistance genes end up in the environment surrounding these farms.

As long as our therapeutic strategy is to kill bacteria, any drug we produce will inevitably select for resistance to that drug (even in people who don’t believe in evolution). One other, far more effective approach is to use the good germs to help us fight the bad ones. As far back as 1958, New York Hospital was able to eradicate a seemingly-intractable Staph. aureus 80/81 epidemic, one that had didn’t flinch at any of the best antibiotics available, merely by proactively inoculating newborns with a different strain of Staph. aureus: the good Staph eliminated the bad Staph. The treatment was cheap (they merely took a nasal swab from a nurse who, doctors observed, had much better luck with the babies she took care of than any of the other nurses did), had no observable side effects, and prevented countless deaths. Why don’t we currently embrace the microbiome transplant as standard therapy and not as a treatment of last resort? Good question.

The benefit of good bugs goes beyond merely crowding out the bad bugs. The “hygiene hypothesis” proposes that many diseases that have been rising in the last couple of centuries are a result from sudden alterations in the microbiome, with whom our immune system has been evolving for millions of years, caused by changes in hygiene, far too recent on an evolutionary scale for our immune system to adapt to. These diseases include not obviously auto-immune diseases, such as serious food allergies and ulcerative colitis, but, some researchers propose that stimulating a patients immune system with a Mycobacterium vaccae vaccine can cure not only autoimmune diseases such as Raynaud’s syndrome and peanut allergies but also diseases whose connection to the immune system is less obvious, such as metastatic melanoma.

No doubt the Dr.s Stanford had a great idea with their M. vaccae vaccine, no doubt they are charming individuals, and no doubt the patients who go to them for the monthly “dirt vaccine” (something that is apparently legal in England) are grateful for feeling better, but the author seems insufficiently skeptical. The patients who came to the Dr.s Stanford for their dirt vaccine, for whom it was ineffective in curing their cancer, are now dead and unable to speak up. The clinical trial designed to test the hypothesis of whether the vaccine actually makes a difference among lung cancer patients showed that it did not. This is why we have clinical trials.

To be fair, if I had inoperable metastatic melanoma, I too would probably start trying crazy therapies like dirt vaccines, and then if my cancer suddenly went into remission, I probably would not say, “Oh, it must have been a coincidence”. We, as humans, are of course all biased. The author, perhaps recognizing that, takes precautions to help strengthen her objectivity: incredibly meticulous, yet unobtrusive, endnotes, one of the greatest features of this book and one that is sadly lacking among too many pop science books. If I think, for example, that the author gives insufficient weight the clinical trial mentioned above, I can look up endnote 64 in Chapter 3 to find the citation in Annals of Oncology, and then head to the library to read the study myself and see whether or not it had the design flaws that the Dr.s Stanford claim. In the same vein, I can look up endnote 65, in which Dr. Stanford claims the supposed benefit among adenocarcinoma patients, to read “John Stanford et al., ‘Successful Immunotherapy with Mycobacterium vaccae in the Treatment of Adenocarcinoma of the Lung,’ unpublished”, and then give that the consideration I think it is due. In this way, if I feel that Jessica Snyder Sachs is at any point insufficiently critical, she has given me the tools to go read the evidence and judge for myself. Not only does it make her book that much stronger, but also it reinforces the point that science is not knowledge handed down from God (as so many science textbooks make it seem to be): every sentence in a science text results from observations, hypotheses, experimentation, and testing, and also plenty of heated arguments. As one of my biology professors from college said, “Every sentence in your textbook has blood behind it.”

And that’s what makes this book a great pop science book. Not only is it on a fascinating subject and carefully researched, as most pop science books are, but it also successfully conveys what science is all about....more

Very readable review of the field of microbiology focused on the bugs that live inside us humans. Loved the first half which taught me a lot of fascinating biology. The second half is more a review of current biotech efforts to battle antibiotic resistance and was somewhat choppy. The book also could use a set of color plates to show us pictures of these bugs. But I loved reading this, even on vacation (where I usually prefer fiction), it was a compelling story.

This book is all about bacteria and how we are getting super strains of bacteria that are resistant to antibiotics. It mentions how bacteria easily transmit certain functionality to one another through the little loops of DNA known as plasmids. There were a couple of other methods of DNA exchange that I forget. The book described the difference between gram-positive and gram-negative. It has to do with whether the bacteria has a hard cell wall, I think.

The book described the difference between gram-positive and gram-negative. It has to do with whether the bacteria has a hard cell wall, I think.

The book spent a long time discussing probiotics. This is a method of finding a harmless or helpful bacteria that competes with an existing harmful bacteria to drive out the more harmful bacteria. The problem with research in probiotics is that companies cannot make a ton of money in the process of discovering bacteria so they don't bother. If they over come that hurdle, FDA regulation is really crazy on the stuff. One of the anecdotes in the book described someone who had discovered a probiotic to protect teeth from cavities. He had to cripple it so that it would not survive outside of its host so he made the bacteria so that it needed a protein that was difficult to acquire. People using the product had to swish with a special mouth wash twice a day. Then the thing went to FDA trials. For his trials, he needed to find people who were toothless, didn't have children, whose partners were also toothless, and were under fifty-five. He found two. He had very good results with his two people, but you typically need more than two people in your studies.

While discussing sepsis, the book made vague mention of cytokine storms. This is why swine flu has affected healthy adults.

Anyway, I enjoyed this book a lot. It made me think a little more about medical regulation and what sucks about it. However, you can see the need for it and why bacteria that someone created in a lab might be treated as a bioweapon instead of a medical possibility.

It turns out that organic farmers who do not use antibiotics for prevention do use probiotics because certain things have been approved for animal use....more

The book reads easily, with real-world anecdotes setting up each chapter's examination of how science has revealed the problems and potential solutions to varying issues.

The book essentially examines humans' relationship with the bacterial world past, present and future. It does not attempt to address any higher or lower level organisms such as fungi or viruses. After reading this, you will understand why the bacterial world is such a significant factor in humans' health. We cannot live without bacteria integrated into our internal ecosphere!

Bacteria have been around for billions of years. That's much longer than multi-cellular life never mind mammals or humans. Humans (as have all other higher life forms) evolved in a world dominated by bacterial life. Our complex systems are tuned to co-existing with the bacterial world, both within us and in our external environment.

The human organism developed natural defenses against bacterial invaders. When humans became "civilized" (gathering into fixed societies from their hunter/gatherer roots) they availed bacteria of an opportunity to develop mechanisms to circumvent humans' defenses. And so scourges literally plagued humankind. In response, humans evolved (by natural selection) to have a hyper vigilant immune system ready to spring into action against the constant onslaught of bacterial invasion.

Along came modern times and humans cleaned up their act, again literally. Sterilization, sanitation and finally antibiotics pushed back the constant onslaught of bacterial assault. However humans still have immune systems on a hair-trigger and this may contribute to why auto-immune syndromes have become so prevalent, particularly in the developed world.

Bacteria naturally quickly evolved "workarounds" to the antibiotics and thus we have anti-biotic resistant bacterial infections on a rapid rise. One of the most fascinating chapters in the book discusses bacterial have gone about circumventing antibiotics and how they freely share their "tricks" with other bacteria, even of other species!

The book examines how the increasing use of multi-antibiotics (that attack using many different chemical weapons) lay wholesale waste to the entire landscape of bacterial fauna within our systems, both good and bad. Killing the good bacteria leaves plenty of room for the resistant bad bacteria to take a firmer footing and so frequently it’s actually counter-productive to use such drastic recourse.

The book discusses the future of fighting bacterial infections – and it’s heartening to know that science does indeed have many clever arrows left in its quiver - they are more strategic than brute force as we learn more about how humans interact and rely upon the microbial world. I leave it to you to read the book to discover the wonder and very very scary mechanisms currently being worked upon – suffice it to say that as science develops weapons against singular bacterial assaults on humans we are simultaneously enabling easy access to developing very very potent biological weapons that can be used against large populations without hope of stopping them.

To sum it up, all of us are a living system with many many good bacteria keeping us healthy. When we get too clean - using antibiotics that not only kill a bad bacteria but also kill good bacteria, we breed resistant bacteria and leave ourselves vulnerable to more bad bacteria. And it's not just us taking antibiotics but it's the entire food industry feeding antibiotics to animals that produce the menu served at the dining table. It's pretty complex but Jessica sums it up at the end saying a return to a more 'balanced' approach may be in the near future.

First book on germs and microbes we live with that is not freaking the ghost out of you from the onset. Rich with newest data, but also provides a very nice and brief introduction into the history of microbes hunt. Accessible, enlightening and outlook expanding.

Since this book was written seven years ago, the information in it undoubtedly needs to be updated, but it is also depressing to realize how much remains the same: doctors are still over-prescribing antibiotics and the use of probiotics to treat (or prevent) disease is still considered fringe for the most part (although I think that everybody now knows that the bacteria in yogurt will help your digestive system, thanks to those Activa commercials.)

And nowhere have I heard that probiotics will help moderate allergies -- which is my own experience -- or that there is solid science and success in treating autoimmune disease and even cancer with probiotic bacteria. Alternative health sites on the Internet do promote the use of probiotic foods to cure all ills, but their claims are often sorely lacking the science to back them up. This book gives you the science, and also helps to weed through the hype that is out there.

It isn't a diet and self-help book; it's a piece of science writing for a popular audience. As such, it takes a lot of complicated science and makes it understandable. It's also a terrifying book in many ways, because it documents the rise and spread of antibiotic infections such as MRSA and C.difficile. So if you're the sort of person who is terrified by reading about that sort of thing, you might want to approach this book in small doses. But I think it *is* still an important book to read, perhaps in conjunction with a newer book such as Missing Microbes (2014)....more

This was a very well-written and not-too-technical science book. It brings in a human element and does a great job explaining antibiotic resistance. The theory that over-sanitation has led to an increase in allergies and auto-immune disease was well-argued and I think there is probably some truth to it. It was fascinating reading about some of the new probiotic treatments and other alternative medicine that is cropping up in an effort to combat antibiotic resistance.

Awesome. Really interesting stuff--presents a whole new perspective on how we deal with bacteria in a world where cleaning products boast of killing 99.9% of germs. "Good Germs, Bad Germs" presents the idea that killing 99.9% of germs may actually be a bad idea--a large percent of these germs are actually beneficial to us, and focusing more on harmony and balance between good and bad germs might need to be our new tactic in the battle against microbial disease.

This is an amazing and highly interesting book. It explaines the why of antibiotic resistance and the science behibd it. Very interesting and extremely pertinent for Anyone, esp young doctors and nurses. Itgoest into phages, reverse vaccine construction, probiotics, etc. i cannot say how very intreiging this informaion is. I superduper enjoyed this and give it the elusive 5 stars that it totally deserves.

I learned a great deal from this book. And to my surprise, I found that I was less afraid of germs, not more, when I finished. I was particularly intrigued by the discussion of probiotics and the interactions of bacterial populations with the human immune system. I also was fascinated by plasmids and the process of horizontal gene transfer between even unrelated bacteria.

Bacterial and fungal diseases had been wiping out people until the later half of the 19th century with the constitution of "Germ Theory" by the highly-intelligent, Louis Pasteur, who finally solved the puzzle and established the link between many diseases and their "causing seeds". This work was further amplified and carried out by other great scientists such as the Nobel Laureate, Robert Koch.

Since the time of Pasteur, who is not included in this remark, we've had this frame of understanding of bacteria as invisible agents who just can't wait to get us! Since we knew of their presence, we've dedicated most of our scientific inquiry to finding out ways of eradicating those ruthless tiny creatures. Our major success was achieved with the discovery of antibiotics (Alexander Fleming and his Penicillin). We rejoiced thinking that we prevailed, the Homo sapiens, over streptococcus, staphylococcus, clostridium, and many other bugs! However, we forgot that there was a flip-side to that coin.

Sachs in her book challenges our current view of the microbial world and offers a pretty sophisticated alternative. What many of us don't know, as Sachs notes, is that bacteria and other microbes aren't all "bad". Our own bodies are microfloras to massive populations of bacteria that happen to be mostly non-harmful, if not useful. When we celebrated antibiotics, we forgot about things such as that bacteria are live organisms that are capable of replicating and evolving at extremely high rates. Our synthetic antibiotics are very powerful at eliminating diseases, but they are also nondiscriminatory in their targeting of microbes: they wipe out the bad ones with the good ones (which constitute the most).

Now what's the problem with that, you say? Well, bacteria, just like any other organism, exist within population that are mostly non-harmful. However, there are minorities that happen to be pathogenic. Such minorities are resistant to our antibiotics, so they survive. Their mere presence in our bodies isn't a threat because their toxicity is a population-dependent action, and because their "good" kind keep them in check. Therefore, when you wipe out most of the population, only the resistant survive replicating and reproducing more and more until they reach sufficient numbers to cause infection. Well then, what do you do? You treat them with more antibiotics, right? but I just told you they're resistant to them, smarty, and you have cultivated that resistance! There you go! I just laid out to you our story of antibiotics which resistance to underlies many deadly infections that modern medicine is helpless against!

Scientists and physicians now understand the risk generated by our non-discriminatory war against microbes. Now we know that we're gonna have to be smarter in our way of treating infections. One great idea that's been introduced is "probiotics" which are, simply, good bacteria used to tackle bad ones. Another great idea is confusing pathogens by manipulating their communications (quroum-sensing) and many great ones that have the potential of curing diseases without disrupting the world within us and outside: the bacterial world.

Jessica Snyder Sachs has a pretty good case to defend in this book. She's a great story-teller, also. The book cites many experts on the subject from the US, Europe, and elsewhere. If you're interested in microbiology, evolutionary biology, medicine, or just in how to live in a bacterial world, then this book is for you.

Bacteria and microbes have long lived on this planet. We're probably just a passing phenomenon in their evolutionary history. They have always been and they will be after we're gone. The better we accept this and understand it, the better our chances of survival in their world. ...more

Good Germs Protect Us From Bad Germs:The good germs that live in and on us protect us from the bad germs, similarly to the way good plants in a garden help prevent weeds from growing. The good germs use up the nutrients so that they are not available to the bad germs. They also change the chemistry of their environment, making it inhospitable to pathogens. Babies initially acquire symbiotic bacteria from their mothers, at birth and when nursing, and later when they inhale air containing bacteriaGood Germs Protect Us From Bad Germs:The good germs that live in and on us protect us from the bad germs, similarly to the way good plants in a garden help prevent weeds from growing. The good germs use up the nutrients so that they are not available to the bad germs. They also change the chemistry of their environment, making it inhospitable to pathogens. Babies initially acquire symbiotic bacteria from their mothers, at birth and when nursing, and later when they inhale air containing bacteria-laden dust particles.

Hygiene Hypothesis:The hygiene hypothesis is the idea children had less asthma, hay fever, eczema and other allergic diseases in the dirty, old days, when they were exposed to more microbes and intestinal parasites that helped teach their immune systems not to over-react to harmless antigens. Some symbiotic bacteria stimulate the body to produce the kinds of cytokines, such as interleukin-10, that calm the immune system.

Problems Caused by Overuse of Antibiotics:Antibiotics kill our intestine’s friendly flora. This can lead to digestive problems, and infections, such as Candida albicans. Antibiotics kill those bacteria of a strain that are susceptible to it, leaving bacteria with drug-resistance genes to thrive and multiply. Drug resistant genes can arise from mutation, but more often these genes are acquired by sex with other species of bacteria that already have these genes. Antibiotics given to farm animals produce drug-resistant pathogens that sometimes find their way into humans.

Rapid Diagnosis Enables Focussed Antibiotics:Doctors often prescribe broad-spectrum antibiotics, because they don’t have time to wait two or three days for the patient’s bacteria to be cultured. But broad-spectrum antibiotics suffer from the defect that they also kill good bacteria. Scientists are working on rapid diagnostic tests that will identify the species of bacteria in only a few hours. The doctor can then prescribe an antibiotic that kills only the pathogen. ...more

This book is a very well researched and well written guide to our hubris as a species. Sachs lays out how our war against microbes has turned out to be more damaging to us than it has been to the microbes that we were fighting. She then explains in detail how a growing cadre of scientists are learning how to work with microbes to prevent and cure disease, rather than trying to eradicate them.

There is probably a great allegory in the book about how it is better to use an enemy's strength against it and the implications of that in modern geopolitics. But I'm not going to go there, because this is a book about science, and science in the public interest. Its worth the read for that. Pay close attention to how irrational fear and cautiousness on the part of world governments have prevented or delayed potential cures for inflammatory bowel disorders, juvenile diabetes, and even tooth decay. ...more

WOW, I had no idea. Sometimes I just enjoy a book that smartens me up.

I loved the case histories, like the two she began with. I wish she could write a book, with 100 case histories, to illustrate the issues like she did here: short, sweet and to-the-point.

Didn't much care for the clinical aspect and it really bogged the book down, when compared to the juicy case histories. I would have to say that MRSA was the star of this book. MRSA: methicillin-resistant Staphylococcus Aureus.

This book provides a history of how we came to understand that germs cause infectious disease, how we have combatted them, and what the unintended consequences of our actions have been (resistant organisms and a hyper-active immune system that without anything to fight, turns on us).

Ms. Sachs asserts that given the improvements in quality and quantity of life during this process, going backwards to unsanitary conditions or forgoing antibiotics, vaccines, and other medical treatments are not reasonable alternatives.

She then suggests that a better solution may be to re-establish our connection with the relatively harmless organisms that have co-evolved with us, take a smarter approach toward harmful bugs, and find other ways to calm our immune system. (e-mail me for a summary with spoilers of the specific suggestions).

An excellent book on the history of human microbiology and the ramificaitons of medical science on the life and wellbeing of not only we humans, but also of the critters who we live with on a daily basis.

Sachs does a good job in attempting to reduce the scientific background needed to understand the complex chemical and biological processes that sum up the interrelationships of bacteria and our body's systems.

Her use of current scholarship and portraying a wide range of therapeutic treatments is extremely interesting, but it does open the door as to the underlying difficulties in the medical bureaucracy in QA-ing each of these treatments. This is not a book you should read if you are close to someone with a debilitating illness as you'll most likely want to jump on the phone to ask them if they've considered some of the experimental treatments detailed within....more

This book was great. It really opens your eyes about our relationship with germs and how we fit together. One truism that I will always remember from this books is the line "In evolution, that which is unavoidable becomes indispensable".

Another thing I learned from this book is the prevalence of treatments for disease that are not pursued because they are not patentable.

Another thing I learned from this book is the prevalence of treatments for disease that are not pursued because they are not patentable. A drug company would have to incur the costs of clinical trials and FDA approval, but would not be able to patent the treatment once it was approved, allowing their competitors to also produce the treatment and reap the benefits without the outlay. Thus there is no incentive for the companies to invest in the treatments, and millions of people suffer each year as a result, of illnesses that could easily have cures. ...more

Such an intriguing and insightful read. I learned a lot about germs. I have even had discussion about a few of the topics in here for people to look at me in disbelief and not believe what I was saying. I will reread this one again here soon to absorb more.

“The 2003 flu season started early in North America, with the first cases showing up in the fall. By Thanksgiving doctors were seeing the usual flu-related pneumonias. As always, the most severe cases resulted from secondary bacterial infections in flu-congested lungs.”
